Sierra Designs Backcountry Bed

The Sierra Designs Backcountry Bed isn't just the most dramatic redesign of the sleeping bag in years – it's also the most comfortable. The 800-fill bag is zipperless. You simply slip into an oval opening and pull the attached cover-quilt around you. It's a welcome change: Whether sleeping on your side, back, or chest, you'll appreciate the warmth and coziness. The bag comes in two-season (rated to 30 degrees) and three-season (rated to 15 degrees) models. [From $350; sierradesigns.com]
